Definitions

  • This application relates to a case and an electronic device having the case.
  • US 4520425 A relates to a control apparatus such as an inverter including a hollow body having generally a rectangular cross-section, composed of sides of sheet metal with upper and lower open ends shielded by cast hollow frames, each having a similar cross-section. Electrical circuit elements are mounted to one of the sides of the hollow body through an opening therein. Ventilating fans are mounted to at least one of the hollow frames for cooling the electrical circuit elements.
  • the case has a fan mounted in a hidden manner, thus addressing the issues that the fan is apt to be invaded by sand wind and rain, and a mounting direction of the fan is from top to bottom which is exactly the same as the direction of gravity, therefore, it is difficult for dust to be accumulated on the fan, and the service life and reliability of the fan are ensured.
  • a lower end and an upper end of the same side wall of the case are respectively provided with at least one air inlet and at least one air outlet.
  • the air inlet of the fan is provided with a dust screen.
  • the mounting mechanism further includes a positioning plate, and the positioning plate has one end fixed to the mounting plate and another end configured to be fixed to a side wall of the case by several fasteners after the mounting plate is inserted into the guide slot.
  • the positioning plate and the mounting plate are configured as an integrally formed structure.
  • a heat dissipator is arranged in the air duct and between the fan and the air outlet.
  • the present application further relates to an electronic device, which includes a case, and a circuit part and a plurality of heat generating elements mounted in the case, and the case is the case according to any one of the above solutions.
  • the case is configured to include a front case body and a rear case body; the plurality of heat generating elements and the air duct of the case are arranged inside the rear case body, and the circuit part is arranged inside the front case body.
  • the present application has the following advantages.
  • an electronic device according to the present application is exemplarily illustrated by taking an inverter as an example.
  • the electronic device includes a case, and a circuit part (not illustrated) and several heat generating elements 14 mounted in the case.
  • a fan 7 and a mounting mechanism for mounting the fan 7 in the case are arranged on a case wall of the case, and an air inlet 5 and an air outlet 3 in communication with the air inlet 5 are arranged in the case wall of the case. It may be appreciated that, the number of the fan 7 is one or more, the number of the air inlet 5 is one or more, and the number of the air outlet 3 is one or more.
  • the fan 7 is arranged inside the case and is located between the air inlet 5 and the air outlet 3.
  • Each of the fan 7 is mounted in a bottom-to-top manner with its air inlet facing downwards and its air outlet facing upwards.
  • the air inlet 5 is located at a lower end of the case, and the air outlet 3 is located at an upper end of the case, and an air duct from bottom to top is formed by the air inlet 5, the fan 7 and the air outlet 3.
  • One or more heat dissipators 6 may be provided in the air duct and between the fan 7 and the air outlet 3.
  • the formed air duct is from bottom to top, which facilitates rapid and uniform heat dissipation of the heat dissipators 6.
  • the case may be configured to include a front case body 1 and a rear case body 2.
  • the heat dissipators 6, the heat generating elements 14 and the air duct of the case and the like have a low waterproofing grade and are thus arranged inside the rear case body 2.
  • the circuit part has a high waterproofing grade and is thus arranged inside the front case body 1.
  • a lower end and an upper end of the same side wall of the case may be respectively provided with at least one air inlet 5 and at least one air outlet 3.
  • the fan 7 is mounted at a lower middle part of the rear case body 2, the air inlet 5 is located at a lower part of the rear case body 2, and the air outlet 3 is located at two sides or an upper part of the rear case body 2, thereby forming the air duct from bottom to top, which facilitates uniform heat dissipation of the heat dissipators 6.
  • the air inlet of each of the fan 7 may be provided with a dust screen, and with the isolation by the dust screen, it is difficult for the sand wind and rain to invade the fan.
  • the mounting direction of the fan 7 is from top to bottom, which is exactly the same as the direction of gravity, therefore, it is difficult for dust to be accumulated on the fan 7, thus ensuring the service life and reliability of the fan 7.
  • the fan 7 can be mounted in various ways, and may be directly fixed or indirectly fixed. In the present application, for ensuring that the fan 7 can be detached and mounted rapidly, the fan 7 is mounted in the case via a mounting mechanism, and reference may be made to Figure 3 .
  • the mounting mechanism may include one mounting plate 8, one guide slot 10, each of the fan 7 is mounted on the mounting plate 8, and the mounting plate 8 is inserted into the guide slot 10 from one side of the guide slot 10.
  • the mounting mechanism may also include two mounting plates 8, one guide slot 10, and in the case that the number of the fan 7 is plural, the multiple fans 7 are divided into two groups and the two groups of the fans 7 are respectively mounted on the two mounting plates 8, and the two mounting plates 8 are inserted into the guide slot 10 respectively from two opposite sides of the guide slot 10, and this is the structure of this embodiment.
  • the mounting mechanism may further include a baffle 12.
  • the baffle 12 is mounted in the guide slot 10, and an end, inserted into the guide slot 10, of the mounting plate 8 is provided with a clamp slot 11.
  • the clamp slot 11 can be engaged with a side of the baffle 12 that is facing the corresponding clamp slot 11 after the mounting plate 8 is inserted into the guide slot 10.
  • the mounting mechanism may further include a positioning plate 13.
  • the positioning plate 13 has one end fixed to the mounting plate 8 and another end configured to be fixed to a side wall of the case by several fasteners (such as screws or bolts) after the mounting plate 8 is inserted into the guide slot 10.
  • the positioning plate 13 and the mounting plate 8 may be configured as an integrally formed structure, to increase the structural strength of the mounting structure.
  • the fan 7 and the mounting plate 8 may form an integrated fan assembly 9, and in the mounting and detaching processes, the fan assembly 9 is regarded as an integrated part, which facilitates the detaching process.
  • the fan assembly 9 is inserted in the guide slot 10 till the clamp slot 11 is engaged with the baffle 12.
  • the mounting plate 8 and the rear case body 2 are fixed by fasteners such as screws or buckles externally, thus ensuring the rapid detaching and mounting of the fan assembly 9.
